TRAIN-HOSE NIPEPLE-ASSEMBLING TOOL.

Application filed February 6, 1925. Serial No. 7,323.

This invention relates to tools for operating on nipples o'l train hose, and comprises all llll] )I.'0YOlllGlliS disclosed in this applica tion. The nriinarv object is to produce an 5 easily made tool which is reliable in; operation.

The above and other objects which will hereinafter appear. are attained by new and useful improven'icnts as disclosed in this ap l0 plication. To enable others skilled in the art to fully understand the essential features of the in'iproven'lents, drawings have been an nexed as a part of this disclosure.

Fig. 1 is a longitudinal section through 3 the barrel on line i i-11 and through the stock on line BB, of Fig. 3.

Fl 2 is a top plan View of the tool.

Fig. 3 is a right end elevation of the tool.

The tool comprises a stock 1 horizontally pivoted at 2 to a carrier or slide 3 for opera tive movement similar to the construction shown for the nipple puller and nipple as sembler in Figs. 9 and 12 of Patent 1,461,- 578.

Stock 1. is provided with a hole 4.- in which is secured by pin 5, the reduced cylindrical end 6 oi the preferably square barrel 7.

Barrel 7 is primarily square to permit ot' its being easily and accurately held while being slotted. F our longitudinal slots 8 are provided in the faces of the barrel. Each two oppositeslots 8 are connected by an end slot 9. A spring wire 10 extends across each end slot 5.) and into the opposite longitudinal slots 8, thence on'icrging to provide two curved portions, which again reenter slots 8 and extend along the slots 8 within stock 1. To prevent the wires from coming out of slots 9, the end portions of the barrel are bent to at least partly close the slots 9. A spring 11 normally pushes a floater or plug 12 against the ends of the wires and barrel. lVhile wires 10 will ordinarily springoutwardly against the inner surface of nipples placed thereon to center the nipples, these wires do not always have sufiicient resilience to be always satisfactory in service, especially in the smaller size used for signal hose nipples. But by providing a relatively pow- 12 against the ends 01 the spring wires 10, the latter are forced outwardly with sulficient force.

In operation, a nipple is slipped over the end of the barrel 7 forcing wires 10 inwardly downward.

0 erful auxiliary spring 11 which forces floater and 'lorcingthe ends of the wires to the left against floater 12 which may move back against spring 11 it wires 10 are forced in suliiciently tar. Thus by the aid of spring 11 the wires 10 press lirmly outward against the inside of the nipple to center it. The lett end ot the nipple abuts against face 13 oi stock 1. As the carrier 3 moves to the right, the neck ot' the nipple is forced into the hose. By making toolsof suitable sizes, the nipples of air.-steam and signal hose can be assembled with the hose.

it is to be noted that the longitudinal center line of barrel 7 is substantially lower than the center line of pivot 2. This insures against the barrel being pushed upward as the neck of the nipple is forced into the hose.

To insure the barrel properly entering the hose nipple an adjusting means is provided between the stool: and carrier. Thus the M stock has a recess 14-,between the lower wall portion 15 of which and the carrier 8, a wedge 16 engages. The upper portion 17 and the rear parts 18 of stock 1 are cut away to provide clearance. lVedge. 16 tapers upwardly to correspond with wall 15, and has a shank portion 19 engaging between pin 20 and head 21 of adjusting screw 22. By adjusting screw 22 upward wedge 16 is forced against wall 15 thereby tilting the outer end of barrel '7 'lqiwardly. By lowering the screw the barrel '7 is permitted to move ll hile this wedge adjustn'ient is shown on an assembling tool, it'is intended for use on both pulling and assembling tool, tor example on such tools as shown in Patent 1,461,578.

All changes which properly come within the spirit and range of equivalency of the following claims are intended to be embraced on within the scope of the claims.

I claim:

1. In a device for operating on train hose nipples, a carrier, a stock pivoted to the carrier, and an adjustable wedge engaging between the carrier and stock at a location below the center of the pivot of the stock to the carrier, thewedge tapering in an upward direction. I y

2. The device set forth in claim 1 with adjustable means'on top of the stock adapted to pull the wedge upwardly.

A nipple assembling .tool comprising.

a barrel having longitudinal slots therein, and spring wires normally having portions thereof in said. slots and other portions outside of said slots, said other portions adapted to be pressed into said slots.

l. The nipple assembling tool set forth in claim 3 in which the barrel is polygonal.

5. The nipple'assenibling tool set forth in claim 3 in which the barrel is polygonal, and with the slots located in opposite faces of the polygonal barrel.

6. A nipple assembling tool comprising, a barrel having slots extending longitudinally on oppo e sides thereof, and a slot across the end of the barrel connecting each two slots on opposite sides of the barrel, and a continuous spring wire engaging in all three said slots.

7. The nipple assembling tool set forth in claim (3 with the slot-ted end of the barrel bent to at least partlyclose said end slot to retain the spring wire herein.

8. A nipple assembling tool comprising, a stock, a barrel secured to the stock and extending outwardly therefrom, and having longitudinal slots in opposite sides of the barrel extending to the extreme end of the barrel which is secured to the stock, wire secured to the barrel and having portions engaging in the slots and adapted to slide beyond the said extreme end of the barrel, and a spring in the stock normally tending to push the ends of said wire portions when said portions project beyond said extreme end of said barre 9. The nipple assembling tool set forth in claim 8 in which/the wire is spring wire.

10. The nipple assembling tool set forth in claim 8 in which a member is interposed between the spring and the ends oi said wire portions.

11. A carrier. stock substantially horizontally pivoted to the carrier, adjnsting means engaging between the stock and carrier at a location substantially lower than the center line of the pivot. a hose nipple assemblingmember secured at one end to the stock and extending outward from the stock, the longitudinal center line 01? the assembling member being substantially lower than the center line of the pivot.
